Jargon is an innovative Chrome extension (Chrome Web Store, Official Website) created by my friend that transforms English web content into learning opportunities using generative AI technology. Launched in June 2024, Jargon offers two types of learning experiences: foreign language learning (Spanish, Chinese, etc.) and English style adaptation (GRE vocabulary, TikTok slang, etc.).
